A. "Unlinking me and my daughters phone: Hello, my daughter and I have shared the same Apple ID for a few years with no problem and one day my daughter came to me and and said our photos were linked[...]"
Avoid Apple ID Sharing:
I recommend not sharing the same Apple ID with anyone whomsoever, as purchases and such can be made, and all else accessible to all users. Make a mistake (i.e. expensive purchase), and it needs to be handled appropriately (with a questionable refund).
B. "[...]is there a way to stay on the same ID, and unlink our photos without losing all our pictures? If you can help me please do!"
About Unlinking Pictures:
If you both want accessibility, then eMail them to one another. If they are on one Apple ID, then they are on one Apple ID - therefore, they will always be accessible with anyone who has access to it.
